Description
Hospira Bacteriostatic Water for Injection USP is the authentic, pharmaceutical-grade sterile diluent manufactured by Hospira (a Pfizer subsidiary since 2015) and imported directly from the United States. This is the same Bacteriostatic Water product used by legitimate US hospitals, compounding pharmacies, and licensed medical practitioners for reconstitution of lyophilized medications — sourced through authentic US pharmaceutical distribution channels, not generic Chinese or Indian-manufactured bacteriostatic water sold by most grey-market vendors. Hospira has been one of the most trusted US pharmaceutical manufacturers for sterile injectable products for decades, and their Bacteriostatic Water for Injection USP is the industry-standard reference product for multi-dose sterile diluent applications. Each 30mL multi-dose vial contains sterile deionized water for injection USP with 0.9% benzyl alcohol added as pharmaceutical-grade bacteriostatic preservative, enabling multiple sterile draws from the same vial within established stability windows. The product is manufactured to USP (United States Pharmacopeia) monograph specifications for Bacteriostatic Water for Injection under US pharmaceutical manufacturing standards. This authentic USA-imported presentation is offered for laboratory research applications requiring genuine pharmaceutical-grade sterile diluent quality — the same product quality used across US pharmacy and research infrastructure.

⚠️ Disclaimer
- This product is intended for laboratory research use only in this offered presentation.
- Not for human or veterinary use.
- Not approved for diagnostic, therapeutic, or medical applications in this presentation.
- Not for use in neonates. Benzyl alcohol has been associated with fatal toxicity (“gasping syndrome”) in neonates and premature infants — this contraindication is standard for all benzyl alcohol-preserved pharmaceutical products.
- Do not use in individuals with known hypersensitivity to benzyl alcohol.
- Handle using appropriate laboratory safety procedures and personal protective equipment.
Authenticity Notice: This product is genuine Hospira Bacteriostatic Water for Injection USP imported through authentic US pharmaceutical distribution channels. Grey-market bacteriostatic water is heavily counterfeited — we source directly through verified US
